低pH值有利于Al2O3與F-反應(yīng)，生成AlF63-、\、Al(OH)F53-、、Al(OH)2F43-.。其含量達到一定值時，離子間發(fā)生締合、水解和濃縮，轉(zhuǎn)化為穩(wěn)定相絡(luò)合氟化鋁Al2(OH)3F3,。在氧化膜微孔中，Al2(OH)3F3是封孔物質(zhì)；在鋁合金表面，Al2(OH)3F3是粉霜；在槽液中，Al2(OH)3F3是渾濁物。所以槽液溶鋁量太大，鋁合金易上粉，槽液易渾濁死槽。緩蝕劑的添加，正是為了保護氧化膜不上粉，降低溶鋁量，延長槽液使用壽命。按實驗結(jié)果，有機醇緩蝕劑的濃度區(qū)間為1-3g/L。（6）螯合劑濃度對封孔質(zhì)量的影響本發(fā)明螯合劑選用乙酸系(如三乙醇胺、乙二胺四乙酸等),磷酸系(如三聚磷酸鈉、焦磷酸鈉、偏磷酸鈉、氨基三甲叉磷酸（ATMP）等)和磷酸基羧酸系（如膦酰基丁烷三羧酸（PBTCA）等），用其強大的螯合鍵能，穩(wěn)定Ti4+和Al3+,確保槽液不渾濁，鋁合金不上粉。按（2）（5）式，pH升高時，容易生成Ti(OH)4和Al2(OH)3F3。這些物質(zhì)，若生成在氧化膜微孔，即為封孔物質(zhì)；若生成在鋁合金表面，即為粉；若生成在槽液中，即為渾濁物。螯合劑的加入，提高了Ti(OH)4和Al2(OH)3F3的生成門檻。螯合劑的用量要特別注意，濃度太高，湖北鋁合金常溫無鎳封孔劑用途，螯合鍵不好打開，封孔能力急劇下降，湖北鋁合金常溫無鎳封孔劑用途。實驗表明，湖北鋁合金常溫無鎳封孔劑用途，恰當?shù)尿蟿舛葹?-3g/L。。</p><div

7）雜質(zhì)離子對封孔質(zhì)量的影響在生產(chǎn)過程中不斷帶進雜質(zhì)離子，造成雜質(zhì)的積累，如NH4+、Na+、K+、Ca2+、Mg2+等陽離子增多，螯合劑消耗加快。因此，把好清洗關(guān)至關(guān)重要。另外，槽液pH過低時，可用氨水調(diào)節(jié)pH值至，不要用氫氧化鈉來調(diào)節(jié)，這樣可有效阻止Na+消耗螯合劑。影響鋁合金無鎳封孔質(zhì)量的因素很多，主要有氟鈦酸濃度、緩蝕劑濃度和螯合劑濃度，這三個因素是決定鋁合金封孔質(zhì)量的關(guān)鍵；槽液的pH值、溫度和封孔時間是影響鋁合金封孔質(zhì)量的重要因素；而提高槽液的潔凈度、減小雜質(zhì)的含量是鋁合金封孔質(zhì)量的重要保證。試驗表明，鋁合金無鎳封孔劑的生產(chǎn)工藝條件應(yīng)為：氟鈦酸（50wt.%）濃度區(qū)間為，緩蝕劑的濃度區(qū)間為1-3g/L，螯合劑濃度區(qū)間為1-3g/L；封孔速度1-3um/min，溫度15-35℃，時間5-15min，PH值。氟鈦酸體系無鎳封孔新技術(shù)有以下創(chuàng)新點：1、采用氟鈦酸作為封孔劑的主要成分，建立了無鎳封孔新藥劑配方及工藝，從源頭徹底消除了鎳鹽對水質(zhì)的污染；2、采用螯合技術(shù)，解決了封孔液分解沉淀問題；3、采用緩蝕技術(shù)，降低溶鋁量，減少表面上粉，延長槽液壽命；4、采用氟鈦酸作為封孔劑的主要成分，封孔速度是鎳鹽的兩倍以上，提高了生產(chǎn)效率。</p><div
